Dc. Mcfarland et al., COMPARISON OF PROTEIN-METABOLISM AND GLUCOSE-UPTAKE IN TURKEY (MELEAGRIS-GALLOPAVO) SATELLITE CELLS AND EMBRYONIC MYOBLASTS IN-VITRO, Comparative biochemistry and physiology. Part A, Physiology, 107(2), 1994, pp. 301-306
Protein synthesis, protein degradation, and glucose uptake were compar
ed in clonal-derived turkey myogenic satellite cells (clone DS-SC) and
embryonic myoblasts (EM) and between satellite cell cultures from Nic
holas (DN) and Merriam's (WM) turkeys. Protein synthesis rates were hi
gher and degradation rates were lower in myotube cultures of D5-SC com
pared with EM (P less than or equal to 0.05). Protein synthesis and de
gradation rates did not differ between cultures of DN and WM (P greate
r than or equal to 0.05). Glucose transport rates were significantly h
igher in EM than DS-SC cultures and did not differ between DN and WM c
ultures. Insulin-like growth factors and insulin stimulated protein sy
nthesis, decreased protein degradation, and increased glucose uptake i
n all cell lines.
